To all whom it may concern: 1 Be it known that I, Fnnmzrcn A. BUCK- NAM,a citizen of the UnitedStates,residing at Auburn, in the county ofCayuga and State of New York, have invented certain new and usefulImprovementsin Disk Gangs for Use inHarrows and Similar TillageImplements, of Which the following is 'a full, clear, and exactspecification.

- vertical pivot points. This object-I accomplish by the employment of anovel and inexpensive form of arm, or lever, pivoted to the verticallyarranged-shaft of the gang members and operating in an improved way toshift said members in a horizontal plane and retain them in adjustedpositions @ne form whichfmy invention may assume is exemplified'in thefollowing description and illustrated in the accompanying drawing, inwhich-' i 1 Figure 1 shows a rear elevation of a disk gang applied to aharrow frame and having my invention embodied therein; Fig.2shows a planview of the shifting arm employed in my device; and Fig.3 shows asideelevation of the same with a portion" thereof broken away for the sakeof clearness. I

Referring in detail to the drawingya, portion of a harrow frame 10 isshown, pro-" vided with a disk gang 11. A forked memher 12,"upon whichis mounted a vertical shaft 13, assists to connect the .disk gang inproper position on the frame; the vertical shaft 13 being mounted in theusual manner in a bearing 14, which bearing is carried on the frame 10,andis' made adjustable thereon for the purpose of permitting changes tobe made in the vertical plane of the gang member, through'the medium ofthe integral wing member 14*.

I For adjusting the gangs in a horizontal] plane, I have provided animproved lever 15, having formed at one end an eye portion 16, whichencompasses and is slightly spaced apart from the vertical shaft 13; Apin 17, I

or similar device, is used for pivoting the lever to the said shaft, andthe space between t e periphery of t e shaft and the surround-Specification of Lettersj Patent. Application filed December 22, 1 13.Serial No. 808,131.

ing wall of the 'eye'portion is sufficient to permit a slight hingedmovement of the lever in a vertical direction. Intermediate theends ofthe lever is an integrally formed sector,-or quadrant, 18, providedwithteeth 19; andformed upon the wing portion of the j bearing l-iii'san upwardly extending detent 20, which is adapted to engage-betweent'heteeth 19 and hold 'the lever- 15 securely against horizontal movement.Adjacent the shaft 13 on'the lever is a casing 21'; within. which. iscarried an extensible coiled spring so I 22,en'gaging at'one-endtheshaft13 and at the other one of: the wallsofth'e casing 2l; in this wayoperating to normally hold'the lever 15in its lowermost position,thereby retaining, in a ylelding manner, engagement 'of'th e "sector 18with the'detent 20.

Whenit'is desired to adjust the disk gangs for the purpose of changin'gtheir cutting 'angles'with respect to-the line of draft, the operatorhas only to grasp the outer end of the lever 15,- andraise it againstthe pressure of the s p'ring 22 a sufficient distance to disengage thesector and detent, whereupon it maybe shift'ed'in either direction, withthe shaft 13 as a center, changing in this way the disk of each memberof the gang. -As

soon'as the operator releases thezlever, the

spring 22 causes to move-downwardly, thereby 'reengaging' the sector anddetent 'justed' positio'n. I

Bythe use of and locking the-disk gang securely'in its a dp I p v myimproved devicethe usual "spring controlled detent is eliminated and theoperation of shifting the leveris in consequence much simplified. Bylocating the sprmg 22 as shown 1n my device, it requires but a minimumof space and'is come pletely out of the way of the other parts of themachine in which .itris used.

An important feature of this construction is to be found initscapacity-for permitting the disks to be changed fromvinthrow tooutthrow, and vice versa, by merely turnloo ing them through an angle of180 on their a vertical axls, 1n whlch 'casethe arm-lever 15, beingextended awayfrom the detent lug, may be easily removed by. withdrawingthe pin 17 and turned about to again coact" therewith. In practice, theframe member 10 usually carries two gangs arranged to straddle arow ofplants, and it is obviously of great advantage to have the direction ofthe r t row reversible.

Another important advantage in connection with my device is that thedetent 20, by reason of being mounted upon the wing portion wof thebearing 1&, maintains a relatively fixed position with the-sector 19 atall times and, regardless of any change in the vertical plane of thedisk gang 11, the sector and detent will always be in proper positionsfor insuring engagement. 7

\Vhile I have shown and'described but one application of my device, itis to be understood, nevertheless, that it is capable of use 1n otherways and, therefore, various adaptations in the location and arrangementof the several parts herein maybe made without departing from the spiritof my invention as disclosed in the appended claims. 7

YWhat I claim as new is:

1. In a tillage implement, a transverse frame member, a disk gangcarrying a ver tical shaft, a bracket to receive said shaft mounteduponthe frame member and movable about a fore and aft pivot, ahorizontally arranged lever on said shaft, a sector on said lever, adetent lug carried on said bracket and projecting upwardly to engage thesector, and means for maintaining said lever and sector in engagedrelations.

2. In a tillage implement, a transverse frame member, a disk gangcarrying a vertical shaft, a bracket to receive said shaft carried onthe frame member and capable of lateral and axial adjustment thereon, ahorizontally arranged hinged lever detach? ably carried on said shaft, asector and detent for said lever and bracket, and means for moving saidlever bodily and yieldingly holding it in position where the sector anddetent are engaged.

,3. In a tillage implement, a disk gang, a pivotal member on which saldd sk gang is carried, a lever hinged thereto, a sector and detent forsaid lever, a housing formed on said lever ad acent to the pivotalmember, and a coiled sprlngca-rried 1n SilldllOHSlng between the pivotalmember and said lever for yleldingly holding sa d sector and detentmengagement.

' 4. In a tillage implement, a frame, a disk gang therefor, a plvotalmember for connecting sa d disk gang to the frame, a lever hin ed tosaid aivotal member a sector formed on said lever, a detent fixed onsaid frame, and means arranged between said pivotal anember and leverand capable of moving said lever bodily about its pivotpoint with saidpvotal member for the purpose of yleldingly holding sa d sector in engagemen-t with the .detent.

In a tillage implement, a frame, a disk gang therefor, a vertical shaftconnected with said gang and rotatably mounted on said frame, a lever"hingedto. said vertical shaft and extending horizontally therefrom,

a sector and detent for said lever, and means arranged between saidvertical shaft and said lever for yieldingly holding said sector anddetent in engagement.

6. In a tillage implement, a frame, a disk gang, a vertical shaftconnected to said disk gang, a bearing adjustably-mounted on saidframeto receive said vertical shaft, a horizontal lever hinged to saidvertical shaft, a sector on said lever, a detent carried on a portion ofsaid bearing in position to engage'with said sector, and means formoving said lever bod ly to yieldingly hold said sector in engagementwith 'the'cletent.

In testimony whereof I afliX my signature, in the presence of twow1tnesses.
